description of Electric Iron introduction: An electric iron is a small appliance‚a handheld piece of equipment with a flat‚ roughly triangular metal surface that‚ when heated‚ is used to press clothes to remove creases. Ironing works by loosening the ties between the long chains of molecules that exist in polymer fiber materials. With the heat and the weight of the ironing plate‚ the fibers are stretched and the fabric maintains its new shape when cool. description: The electric iron must have a design

A Case of Iron Deficiency (Summarizing and Note-Taking) Describe the structure of a molecule of hemoglobin and explain the role played by iron in the transport of oxygen. The structure of hemoglobin is a hemi group. A hemi group consists of an iron (Fe) ion held in a heterocyclic ring. Iron binds with oxygen. Therefore‚ it has a very important role in transporting oxygen in the blood. How is iron stored and transported in the body? Iron can be stored within intestinal entrecotes bound to ferritin

Iron deficient anemia is a decreased total iron body content. It occurs when iron deficiency is severe enough to lower the amount of red blood cells being formed and it causes the development of anemia. It is the most common deficiency in the world. Hemorrhages can also cause anemia and much greater problems. Bleeding can also be so slow that it is often overlooked.
